Thank you, Daniel.
The problem is solved! I found out that both global and local package db get
directory-22.214.171.124 and process-126.96.36.199. I unregistered them and other caused
broken packages in the local package db. Then I successfully installed back
hmatrix, ghc-mod, happy and etc. It seems that xmobar will install
directory-188.8.131.52 again in the local package db.
Did you succeed in installing haddock 2.9? Mine got some syntax oriented
error duing cabal install haddock. But it's fine.
